My invention consists .in a. new and iin- .V

- proved brick-machine, which will be hereinafter fully described and claimed. j

. Referring to the several parts by their designating-numerals, 1 1 indicate the sidevpieces 'of the frame of my new and improved brickl machine, and 2 a horizontal platform,'which is secured in the frame at what may be called the front end portionfof the same. This platform 2 has formed in it thennolds 3.3, formed side by side, as shown,while below "these molds is secured. the adjustable moldboard or guideboard 4, which is formed with the two openings 5 5, through which work the lower compressor-blocks, 6 6, hereinafter dev scribed. This'guide-board 4 is adj ustably secured at its ends by the setlscrews 7 7, which Vpass through theslottedend irons8 8, 'as shown, by means of which arrangement ythe said board ternately one after the other.

can be adjustedvertically to increasethesize` of the mold when a larger'quantityfofclay has tobe used for each brick, owingto the clay being damp, the size of the two moldsgor rather their capacity, being thus adjusted to suit the condition of the vclay byper-mitting the lower compressorblocks to fall a greater f 'or less distance, as shown in Fig. 8.

Near the center of theupper part of the 'nua-V chine is journaled transversely the drive- Vshaft, having mounted upon one of its ends n the gear-wheel 10, 'and having the operating crank: or handle 1.1, by means `of which'it is revolved when themachineis to be driven by hand, while below this gear-wheel 1'0 is journaled on a stub-aXle, 12, on thatsideof the 'machine-frame a pinion, 13,. ofabout` oneeighth ythe size of the gear-wheel and' meshing therewith, while outside lof this pinion is mounted upon the stub-axle a band-wheeL-lei, for the reception of the drive bandor belt from the source of power, by which arrangement the machinev can be driven bysteamplorlY l Y (75.- In the rear endofthemachineframeisjour-L j naled transversely in bearings a shaft,; 16,

upon which are secured the two eccentrics 17 1 18,.'andupon'one end of -this shaft is secured` a large gear-wheel, 19, which meshes vwith the` large gearfwheel 10 upon the drive-shaft 9.

Upon the rear half of the/,platform y2 are;

guideways 20, between whichslidel andrecip;V rocate the combined feed-slides anddischargelframes, each of which consists of'al block,21,

to the forward end of which is securedthe metal square'frame 22, while the rear ,endfofV the block has arecess, 23', in which ispivoted one end of a pitman, 24.'` Each of the sai'dtwo pitmen 24 has secured to its rear end they cir"-A cular band 25, thesaid metal rigid bands passing around the eccentrics 17 18, as shown.;V

.These eccentrics 17 18 are securedl up'on the shaft 16 so that they extend out from thesarne opposite to each other, by whicharran'g'ement it will be seen that as the shaft 16 revolves one leccentric will, .through its pitman 24,force its slidey 21 forward, while the other'eccentri'c` draws its slide 22 back, so that'thel said feed and discharge slides or frames will .operate al-` Upon the central upperppart `offtlie machine-frame isse-V IQo l cured the feed-hopper 26, through which the blocks of clay are fed down into the feedframes 21 22.

In the upper forward part of the machinef rame is j ournaleda transverse shaft,27 ,havin g on one ofits ends a large gear-wheel, 28, which meshes with the gear-wheel 10 of the driveshaft 9, while upon the middle portion of this upper shaft are secured two eccentrics, 29 30, placed so as to extend out opposite to-each other in a similar manner to the eccentrics 17 and 18 on shaft 16. Below this upper shaft, 27, is secured in the machine-frame acrossbar, 31, this bar being arranged above the platform in which are the molds 3 3, and this cross-bar has formed in it the two guide-openings 32 32 in vertical line with the said molds. Through these guide-openings slide and reciprocate the plungers or upper compressors, 33 33, the lower ends or heads of which are formed of the exact size of the molds 3 3, while the upper ends of these plungers are recessed vertically to form the wide parallel side pieces or jaws, 34 34. Between these jaws are pivoted the lower fiat ends of the short pitmanarms 35 35, to the upper ends of which are secured the rigid metal circular bands 36 36, which t around the eccentrics 29 30 on the upper shaft, 27, as shown.

Beneath the platform 2 is journaled transversely the shaft 38, on the outer projecting end of which is secured a gear-wheel, 39,which meshes with the large gear-wheel on the driveshaft, being of the same size; and upon the middle portion of this lower shaft,which is journaled in line below the mold-openings of the platform 2, are secured the two cams 40, which are secured upon the shaft with their projecting ends opposite to one another, so as to work alternately. Above these cams are secured in the openings 5 5 of the adjustable guide-board 4 the lower compressorblocks, ,6

6, which are operated by the' said cams, being pressed up by the same, and fall down by their own weight when the projections of the cams pass from under them.

It will be seen from theforegoing that the two feed-slides, the two plungers, and the two lower compressors operated by the cams work alternately, one feed-frame, plunger, and lower compressor operating together. Now, in operation, the blocks of clay are placed in the hopper and theseveral shafts are revolved by the drive-shaft by hand or steam or other power. As the feed slides or frames 21 22 are `reciprocated alternately, each end frame, 22,

as it comes beneath `the bottom of the feedhopper, will receive a block` of clay, and as the slide moves forward it will carry .this clay reception of -the clay block. The block being thus dropped in the mold,as the shaft 16 continues its revolution this feed-frame above referred to is drawn back, while the other feedframe slides forward, having received a clay block in it from the feed-hopper. Now,as the first-mentioned feed-frame is thus drawn back,

the cam 40 on its side raises the lower plunger or compressor-block, 6, while the eccentric of the upper shaft on thatsidc forces that plunger 33 down, so that the brick is thus tightly and thoroughly compressed in the mold, the guideboard 4 having previously been adjusted vertically according to the condition of the clay, whether damp or dry, as previously described, as a greater quantity of damp clay is required to make a brick of a stated size than when the clay is dry. While the brick in the righthand mold is thus being compressed,the lefthand feed-frame has been slid forward,so as to deposit the clay block which'it received from the feed-hopperinto theleft-hand mold,the lefthand plunger 33 and compressor-block 6 being drawn back to open and leave clear the left-hand mold.` Now, as the revolutions of the shafts continue, the left-hand pl ungers will be forced into the'mold to compress the brick contained therein, while the empty left-hand feed-frame is drawn back to receive another block of clay from the hopper, and at the same time the right-hand feed-frame, which has received a clay block from the hopper when the left-hand brick was being compressed, is` slid forward, and as it `moves forward the front end of its frame will push forward out of the wayth'e finished brick which was just before compressed in the right-hand mold, and which is held up flush with the top of the table or platform 2 by the lower compression-block, 6, which is held in its elevated position by the continued raised end of its cam 40, the said cams being constructed in the form shown, so that after pressing the brick from below as the upper plunger, 33, presses it from above they will retain the lower presser-blockl up in its elevated position, while the upper plunger is raised and the feed-frame slides forward, holding it up thus until the square frame 22 of the feed-slide has passed over it and pushed the finished brick forward clear of the mold, when the cam-point passes from beneath the lower end of the lower block, 6, and lets the said block fall by its own weight to open the mold and enable the clay block in the feed-frame to enter the mold ready to be compressed as the plungers are again forced in.

It will be seen thatthe feed-frame acts not only as a feed, but also as an automatic dis-A IOU the construction and manner of `operation ofm y invention will b e readily understood-g It will be seen that it is simple and strong in construction and exceedingly rapid, accurate,` and efficient in its operation, possessing many decided advantages, which` will vbe readily seen and appreciated. It will be seen that by the several parts o n each y side working alternately `not only will the machine perform-its work with rapidity, but that only one-half the power will be required to, run it that would be re= quired if the two sels of plungers operated at the same instant to press the two'bricks at the Vsame moment. .This advantage will bereadily seen, as only sufficient, power is required to press one brick at a time. The alternating parts also counterbalance eachother to a great f extent and assistfin causing the `machineto the proper time.V

run lightly and easily. Thespeed can be increased or lessenedas desired, as all the parts willmove so as to beat the correct points at Instead of the straight shafts y16 and 27,

l havingthe eccentrics o'n each, I- may employ t 25 a doub1ecranked shaft inplace of each ofthe said shafts; but I prefer touseY the straight shafts with the eccentrics, most especially in the caseof the upper shaft,'27, which operates the plungers 33 33."` `If a double-cranked shaft were used to operate theseplungers, the recessed upper ends of 4the plunger's 33 33 would .v be pivotally connected to the pins of the said double 4cranks by means of straight pitmen,

\ and it will be readilyseen that as the crankedy 35 shaft revolved and the plungers-were forced down to press the bricks the said pitmen would stand/fron; the ybeginning ofthe downwardstroke at a considerable inclination from theivertical, (forty-five degrees or more,) and that instead of thepressure on theplungers being straight down, when it is most lneeded I in pressing the brick in the molds,.fthe pressure would be ata greatinclination onfthe upper ends of the plungers, which would thus not .be pushed squarely down and would be likely to stick or -bind in the guide-openings through which they pass, and would not enter the molds molds.

the plungersdown fairly and squarelyupon the clay in the molds, the power beingV all exerted H in a vertical or nearly vertical line. AOil-cups may be arranged above theV eccentrics,(on/,the

y. circular bands' or otherwise, to keep `the parts well lubricated and reduce friction.r g ,t e It will be seen that instead of a two-brick machine the capacity of the machine may be increased to'afour-brick machine, or, infact, Y

vup to any number, by increasing the widthj` of the machine and the number ofthe rsetsofg, feed-frames, eccentrics, plungers,molds', &c.1
